Alibaba Group Holding Ltd (BABA) shares closed at $159.72 on November 18, 2025, up 1.27%, following the launch of a public test phase for its new AI assistant and intensified AI collaboration efforts[2]. This positive momentum comes after a sharp decline on November 14, 2025, when shares fell 3.78% to $153.80 after a Financial Times report alleged Alibaba’s involvement in providing data and AI services to the Chinese military, triggering securities fraud investigations[3][5][6]. Recent price action reflects renewed optimism around Alibaba’s tech initiatives and easing regulatory uncertainty, but ongoing legal and geopolitical risks remain in focus. The stock’s rebound suggests investors are weighing long-term growth prospects in AI and cloud against persistent headline risks.
